Be itknown't atI, JOHN SonENsEN, av citizen ofthe United States, residing atv Ottawa, inthe county ofLa Salle and State f of Illinois, have invented afcertain. new and useful Improvement inRadiator Cores,=of`

which the Afollowin 1s a full, clear, concise, and exact descript1onreference belng had to the.acoompanying1`.drawings, formlng a part of this specification.

This. invention relates to radiator cores,

and more particularly to a radiator core having space sages extending from'top to bottom of said continuous tortuous v water pasradiator, and 'intervening air passages provided with partitions that act as-deflctor plates for the air passing through said passages so aSto cause the vair to have a greater cooling effect on the water in the'saidl radiator.

It is a purpose of the invention to provide a radlator core having the above mentioned characteristics, that is, madaup of pairs of sheet metal members forming a water passage between them, alternating with spacing reinforcing members that serve as deflector partitions in said air passages.

It is a further purpose of this lnvention I to providea radiator core having continuous water passages extending from top to bottom thereof, the wallsof said water passages be- I ing formed by a pair of sheet metal members that are provided with arcuate corrugations curved downwardly from the center toward the front and rear ends of said core, which water passages alternate with air passages having partltions therein comprising sheet metal members provided with arcuate cdrrugations extending in a direction opposite to that of the corrugations of the 'members forming the walls' of said water passages.

It is another object lof the invention to'y provide a radiator core with watercontaining members that are'each made up of a pair of corrugated sheet metal members that are made alike but merely faced in opposite directions ,to 'form a water passage between them. This is accomplished by corrugating the edge ortions more deeply than the central portions of the sheet metal members.

It is a further purpose of the invention to l provide means` in the air passages of said radiator core that serve to compensate-for the expansion of said `waterlchambers due Specification of'Letters Patent.

to freezing or othercauses, and' cause said water passages to resume their original shape and position after the expansion force 1s removed.

'It is a still further object of the invention Atoprovide a radiator core having tortuous 'air and water passages that Vare so constructed .that there will be no possibility of clog-- glng elth'er of these passages byany foreign matter that ymay pass therethrough, and to provide a radiator core'that can'be readily cleaned. .y

It is' also a'further purpose ofthe-invention to provide-a radiator core with separating .or air deflecting elements whose edge portions are corrugated deeper than the central curved portion thereof, thus causing an excess of material in the central curved portion, which causesthese elements to return -to normal position after flattenin to a cerform that my invention may take, proceeds.V However, I desire to have it distinctly understood that I do not intend to limit myself to the exact details shown therein and described in the specificatiombutdesire to include as part of my invention all such obviouschanges as would occur to a person skilled in this art and as would fall within the scope of the claims.' l

This application is a substitute for the application filed by Lawrence Skow, Morris raus and John Sorensen, Serial INo. 345,937, filed Dec. 19, 1919 for radiator core, as joint inventors. v

Referring in detail tothe drawings Fig.

8 made in accordance with the present 'in- The radiator core is made up of a plurality of sheet metal members pairs of which form water containing chambers.

or passages and others of which form spacing means or defiector elements between the water containing members. The water containing members are madeup of two sheet metal pl-ates that 'are similar in form, being made in the form shown in Fig. 5, and these are oppositely arranged so that the 4sides thereof confront each other.

Referring'to Fig. 5 the members forming the walls of the Water chambers are .corrugated so as to provide curved corrugated raised portions 9 and strai ht corrugated raised end portions 10. hese alternate with depressed or oppositely corrugated curved central portions '11 and straight end portions 12, the corrugations at 12 being deeper than the corrugations at'9, 10 and 11 so that when the elements are arranged in such a manner that-the corrugation's 11 of one member rest in the recesses provided by the c'orrugations 9 of the other member,

the portions 12 will contact with the portions 10 in such amanner as to space the two plates from each other throughout the curved corrugated portions thereof from ed e to edge.

n Fig. 4 the plates forming the walls of the water, channels are referred to by the numeral 13, and it will be seenth'at in the manner just described water passages or channels 14 are provided between the sheet metal members 13 extending from the top to the bottom of the radiator and forming'a tortuous channel from top to bottom. The watel` channels are so arranged that the curved portions ofthe walls extend iny the same direction for each of the water containing members and these are so arranged that the central portions of the curvedpart9 or 11 are higher when in the radiator than the end portions thereof. Thus in Fig. 2 the central portions 15 of the lwater containing members .are shown as being higher than the end portions '16 thereof. Between the water channels air passages 17 are formed and these will haveside walls corresponding` to the shape of the walls of the water containing members,that is, they will be corrugated and these corrugations will be curved as is shown in Fig. 5. Interposed between the water containing members and located in the air passages are the partitions or air deector elements 18; one of these is shown in fragmentary perspective viewin Fig 6.

the members that form the walls of the water containing` members and Vare' provi ded with curved corrugations 19 and 20 extending in opposlte directions. 'The curvature ,of the corru ations, however, is always in the same directlon just as withthe 'members forming the walls for the water containers, but when these arefassembled withv the' 'water container elements the corrugations araso arranged that they curve thel oppositedirection to those of the water container elements, that is the lowest'point 'of the ,curve willbe in the center andthe. end portions will be higher. The end portions' 21 of the spacing or deflector elements 18 are made straight as` in the case of the elements forming the walls for the water containers, and these are corrugated more deeply than e the central portions of the sheet thus providing an excess of4 material in the central portions. 'The corrugations at 21 .are provided with grooves or.

while the parts are being soldered together. f

The ends of the radiator are dipped` in solder vso that the corrugations 12 of one sheet, the corrugationslO of another sheet and the portions-22 of the partition member are united throughout the edgeportions of the' corel; while the central portions are spaced as is' shown in Fig-3 so as to form water containing channels or passages 14 between the members 13 and `tir passages be# tween each member 18 and the adjacent members 13.

It will be noted on an inspection of Fig. 3 that the crests of 'the corrugations 19 .do not touch throughout the entire curved corrugated part of the core, ybut that a slight space is provided between them at 23. Each of the air channels will have a wallon one side that is corrugated and curved so as tohave ythe highest points ofthe curves of the corrugations upwardly and the other side 'with the highest points of the curves of the lcorrugations downwardly, thus forminga channel of constantly varying width and cross sectional outline andin that way providing a tortuous pas'sage'fo'r the air so 'that the maximum cooling effect thereof titions are the curves of the corrugations such that they recurve and thus a passageway is provided that offers considerable rc-V sistance tothe passage of air therethrough and provldes a large amount of Wall'are'a for the alr passages and the Water 'containing elements, While at the same timffclo- E:

leakage results.

ging of the air passages is prevented as any foreign matter would readily pass there-- through as there is no reentrant portion in which such foreign matter could lodge. In case any foreign matter should become lodged in the passages it can be readily removed byfloating the same out with water or forcing it out with steam or compressed air as the passages are such that the foreign matter can be easily forced out of the same as the curves of the corrugations are not so sharp as to prevent this. As none of the various elements `touch each other, except at the edge portions thereof, a radiator is provided that has a great degree of flexibilit and which can expand considerably without any-harm thereto that would result in leakage. In the case of freezing the elements 13 would expand so as to separate from each other further and would approach the corrugations 19 or 20 of the spacing elements and with further expansion would contact with these corrugations and would tend to flatten them. However, due to the manner in which the spacing or partition elements are constructed with an excess of material in the curved corrugated part thereof these have a certain amount of resiliency and tend to return totheir normal position, consequently when the ice formed in the frozen radiator thaws thepartitions or spacing elements will tend to return .the

members 13 to their original position wherever the two parts are in contact. While the spacing such as at 23 would probably not exist throughout the radiator after such freezing has taken place as would distort the partition member the radiator would be restored so nearly to its normal position that the freezing will do no harm thereto even where the4 radiator is frozen solid and no Having thus described my invention what I claim and desire to secure by U. S. Letters Patent is 1. In a radiator core a plurality of spaced Water container members providing air pas.-
